12381,[4.3.0 regression] VirtualBox keeps crashing the host OS (constant kernel panics),Artem S. Tashkinov,,"Host OS: Linux 3.12 vanilla, i686, PAE, 16GB RAM, Intel Core i5 2500 [[br]]
Guest OS: Windows XP SP3, i686, English, vanilla, no patches, no software, just VBox additions.

GuestOS parameters:
{{{
RAM: 640MB
IO Apic: ON
Processor: 1 or 2 (crashes anyway)
Execution Cap: Off (100%)
Acceleration: Full (VT-x + Nested Pages)
3D acceleration: Off (I'm not using 3D apps anyway)
2D video acceleration: on
VidMem: 30M
Monitor: 1
PAE/NX: disabled
Chipset: PIIX3
Pointing Device: PS/2 Mouse
EFI: Off
UTC HW Clock: Off
}}}

Guest has only 2D acceleration turned on and it has no audio enabled. I'm not doing any fancy stuff - crashes occur when the guest is fully idling. It more often crashes when I'm playing audio on my host (seems like playing audio on the host triggers the bug faster).

4.3.3 build 90796 crashes too. 4.2.x has never crashed here.

I cannot show you kernel panics, because my /var/log/messages is empty on reboot.",defect,closed,other,VirtualBox 4.3.0,fixed,,,Windows,Linux
